0
Pin SDOUT functions as serial readout (<SERIAL READOUT> = 1)
0
Pin SDOUT is NOT in high-impedance state; it is forced low by the device (<SERIAL READOUT> = 0)

The reset pulse is needed only when using the serial interface configuration. If the pulse width is greater than 1usec, the device could
enter the parallel configuration mode briefly and then return back to serial interface mode.
